Embodiment 1

[0024] (1) Processing and installation of round steel pipe supports: The round steel pipe supports are processed by Φ299*10mm round pipes. The height can be adjusted by the longitudinal and transverse slopes to ensure that the top surface is level or not more than 1% slope. A 400*400*20mmQ235 steel plate is welded on the upper and lower ends. The round steel pipe supports are manually transported and installed, and the lower end is welded to the steel box girder overhangs, with a spacing of 4.65m. The round steel pipes can be replaced by materials such as I-beams.

[0025] (2) Longitudinal slide beam processing and installation: The longitudinal slide beam is processed by 45b I-beam, and the length of a single group is 12m. The I-beam is welded with a stiffening plate along the longitudinal spacing of 50cm. The stiffening plate is processed by Q235 steel plate with upper bottom 410mm, lower bottom 425mm, height 60mm, and thickness 10mm. After the stiffening plate is welded, the ...

Abstract

The invention discloses an installation device of a prefabricated bridge deck, which belongs to the field of bridge construction. The installation device comprises two longitudinal slide-way beams which are symmetrically and fixedly distributed on a top overhanging eave of a steel box beam in parallel, two transverse bearing beams which stretch across the two longitudinal slide-way beams and symmetrically arranged on the two longitudinal slide-way beams in parallel as well as two parallel symmetric longitudinal bearing beams which stretch across the two transverse bearing beams, wherein each longitudinal slide-way beam is respectively provided with a carrying tank and a limiting distribution device which is used for supporting the transverse bearing beam to slide back and forth along the longitudinal direction, each longitudinal slide-way beam is also provided with a gallows, and the gallows is connected to the limiting distribution device through a traction rope and pulls the carrying tank to slide on the longitudinal slide-way beam. The installation device can solve the problem that the prefabricated bridge deck is subjected to the limitation of the installation terrain and is safe to use, convenient and high-efficient to operate and easy to control.

Description

Technical field [0001] The invention belongs to the field of bridge construction, and particularly relates to the field of installation of steel-concrete composite beam prefabricated bridge decks. Background technique [0002] The steel-concrete composite beam prefabricated bridge deck is generally prefabricated near the bridge, and the weight of a single piece is about 30t. After the steel beam is erected, it is installed on the ground near the bridge by a large-tonnage crawler crane or a car crane. Due to the limitations of the site's topography, some bridge decks cannot be hoisted and installed with existing technology and equipment. Summary of the invention [0003] The purpose of the present invention is to provide an installation device for the prefabricated bridge deck that solves the problem that the installation of the prefabricated bridge deck is restricted by the terrain, is safe to use, is convenient and efficient, and is easy to control. [0004] The purpose of the pre...
